This invention relates to a siphoning apparatus whereby liquids may betransferred from one vessel to another, and has for its principal objectto provide a device of the above character in which there is embodied asa part thereof a suction pump that may be operated to create thenecessary suction to start the siphoning action.

Other objects of the invention reside in the provision of a valve in theconnection that is operable to control the flow of liquid after thesiphoning action has been started.

Still further objects of the invention reside in the various details ofconstruction and in the combination of parts and in their mode ofoperation, as will be hereinafter described.

In accomplishing these and other objects of the invention, I haveprovided the im proved details of constructiomthe preferred forms ofwhich are illustrated in the accompanying drawings, wherein- Figure 1 isa side view of a siphoning apparatus embodied by the present invention,il-

lustrating its relation, when in use, to receptacles between whichliquid is being trans ferred.

Figure 2 is an enlarged, longitudinal section of the pump and the valvemechanism embodied in the system.

Referring more in detail to the drawings 1 designates what may be a pumpcylinder of the ordinary type of construction, where in there iscontained a pump piston 2 operable by means of a piston rod 3 thatextends slidably through a perforated end cap 4 that is threaded ontoone end of the cylinder. At its outer end, the rod is equipped with ahandle portion, here shown in the form of a ring 5, whereby the rod andpiston may be moved reciprocally. The piston 2 is provided with a port 6within which is a ball check valve 7 that operates automatically whenthe piston is moved outwardly to close the port and which opens when thepiston is moved inwardly.

Extended along the outside of the pump cylinder is a tube 9 having oneend bent laterally away from the cylinder and equipped at its outer endwith a valve, or stop cook, 10.

This tube connects, by means of a passage 11, with the base of the pumpcylinder. Fitted onto the valve is a flexible extension tube 13, ofrubber or other suitable material, of a desirable length adapted forapplication into the vessel or receptacle, as indicated at 14: in Figure1, from which liquid is to be removed. Assuming the parts to be soconstructed, the use of the device would be as follows:

With the pump piston moved inwardly to its limit of travel and with thevalve 10 open while the other end of the tube is closed tightly by thefinger of the operator, or any other suitable means, the tube 13 isinserted in the liquid to be transferred from the vessel 14: into anyother receptacle, such as the vcs sel 16 shown in Figure 1. The piston 2is then drawn outwardly by means of the rod 3 thereby creating a suctionwithin the pump that will act to draw the liquid from the vessel 14through the tube 13. This pumping action, if necessary, could berepeated until the tube is filled with liquid. Then, the outlet of thetube 9, which necessarily must be at a lower horizontal level than thereceiving end of the tube 13, is uncovered to permit an outflow of theliquid into the vessel 16. By

virtue of the well-known siphoning action thus produced, the flow willcontinue and its rate may be controlled by adjustment of the valve 10.

It is apparent that such devices could be made in various sizes withtubes of various lengths and that various details of constructioncouldbe departed from without departing from the spirit of theinvention, and, for this reason, I do not wish to be limited only to thedetails shown. It is intended, in this particular instance, that thedevice be cast from hard rubber or the like and thus the cylinder andthe tube 9 may be provided in a single, integral piece.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters Patent, is:

A device of the character described comprising a pump cylinder, a pistonoperable in the cylinder to create suction, a tube formed integral withthe cylinder wall lengthwise of the latter and having an open- T no.
